SkyOS build 6814 has been released. Among its new features are streaming support, system-wide spell checking, the Mozilla embedded Gecko engine (which is used to create a few applications like a Wikipedia reader), an updated Viewer (file manager), a new theme engine, and more.

You havent understood the point, kaiwai. There will come a time where an os is dead because of various reasons ( like the creater has no interest in developing it anymore or publischer out of businnes or in case if windows vista - inferior successor ). Now, if we had a source, we would just fixed it ourselves, if there were any interest, but since we don't ( like with beos ) people ( in a way )wasted a lot of time and resources trying to recreate it.

I think the point was very relevant because as we move on the hardware changes are accompanied with software changes, if the software is proprietary, it's dead if it's no longer updated. Assume robert ist struck by lightning or doesn't have any interest in developing it anymore. Now where does that leave the devoted users? Have the source = the os can be updated by the interested people( it continues to exist in this software/hardware cycle ) / no source = as less and less hardware is able to run it it becomes a faint nostalgic memory.

Creating a proprietary operating system nowerdays is a step backward. And by this i mean not software in general. Since os'es become more and more complex, they demand more and more resources and components to be functional. And no single entity can hire as much resources as a crowd of interested people can provide for free for the sake of interest or common good or even commercial interest. Even apple incorporates more and more open source technologies like khtml and zfs. And in contrast to that look at microsoft and their open source phobia and how much it hurt for example internet explorer.
